SCIENTIFIC METHOD SCIENTISTS STEPS
Discussion: The activity includes words that are related to the scientific method. Discuss the answers of the students and how did they find each of the hidden words. The following questions should also be answered by the students:
1. What do you know about each of the words in the activity?
2. How do each of the words relate in the Scientific Method?
3.
Are there any more words that can be found in the puzzle that is also connected to Scientific Method? What are those words and how are they related to Scientific Method?
Input: Review the students in the definition of the Scientific Method and what are the steps or procedures in it.
The Scientific Method is the scientific approach to answering a problem.
1. Ask a question – determine a natural phenomenon that you are curious about.
2. Research a topic – this includes reading books, notes or journals and surfing the internet
3. Formulate a hypothesis – using the knowledge that you have gathered, formulate a hypothesis about the cause of the phenomenon you are curious about
Hypothesis is an educated guess about the answer or solution in the studied phenomenon.
4. Test the hypothesis – includes planning and carrying out a procedure, usually an experiment, which would test test the hypothesis you have formulated by gathering data.
Data are the information gathered during an experiment.
5. Analyze the data – use proper analysis to see if the data gathered supports or contests the your hypothesis.
Deepening:
Ask the students how they would apply the Scientific Method in the following …show more content…
situations:
(1) Flower Power
SpongeBob loves to garden and wants to grow lots of pink flowers for his pal Sandy.
He bought a special Flower Power fertilizer to see if will help plants produce more flowers. He plants two plants of the same size in separate containers with the same amount of potting soil. He places one plant in a sunny window and waters it every day with fertilized water. He places the other plant on a shelf in a closet and waters it with plain water every other day.
• What did SpongeBob do wrong in this experiment? Explain.
Answer: SpongeBob did not provide both plants with the same amount of water and sunshine. In order to test the fertilizer correctly, both plants should have been placed in the sunny window and watered every day withthe same amount of water. The only dif erence between the two plants should have been the fertilizer - one plant would be watered with the water with fertilizer and the other would be watered with plain water.
• What should SpongeBob do to test the effectiveness of Flower Power fertilizer?
Answer: The experiments may vary as long as they address the problem of SpongeBob.
(2) Bubble Time
Patrick loves bubble gum and would like to be able to blow bigger bubbles than anyone else in
Bikini Bottom. To prepare for the Bikini Bottom Big Bubble Contest, he bought five different brands
of bubble gum and needs your help to find the brand that creates the biggest bubbles.
• How can Patrick apply the Scientific Method to win the contest?
Answer: Answers will vary. Students should make sure to perform the same test with each brand in order to obtain reliable results. Repeated trials would generate more data to analyze and help Patrick pick the best bubble gum brand for the bubble blowing contest
Synthesis:
Group Work. Divide the class into ten groups. Each group must appoint a speaker that would present their work after the activity. Ask each of the groups to give a situation or a problem that can be solved by scientific method. Provide each group with a piece paper to write their answers. When all of the groups are done discussing and writing their answers, ask the speakers to present their work in front of the class and explain how they arrived at their answer.
